1. Press the "spin" button and then press the spacebar to stop each panel. The panels will then slow down and stop. 2. If you don't match 3 panels, then you can press "spin" again. If you do match 3 then a number like +50 or +1000 will pop up. These don't do anything yet. Remember: Every time you spin again, press the "spin" button twice because the two last panels are somehow slower and to fix it you must press it a second time.
I was mostly inspired by the Super Mario Bros. 2 slots at the end of each level.
